This idea is based off the "Nitemare Cafe". A living Hotel, the "OtherWorldInn" takes people who have various special needs for their life, or unlife, as it were, and grants them wishes, using the staff of the Inn, to help or hinder it's guests.
Basically, the first guests are not undead, but they have died before, brought to life by the mysterious Inn. It's manager, an NPC, known as Smokey, is an eccentric person known for his enigmatic nature. He's been in the Inn for longer than anyone else who's there.
Be warned that rapists and the like who abuse others will most likely earn even far worse pain and suffering than they inflict on others, from the Inn.
